Quality of pre-sprouted sugarcane seedlings grown on substrates with decomposed babassu palm stem

ABSTRACT The use of pre-sprouted seedlings in the implantation sugarcane crops not only reduces establishment period and production costs, but also has other advantages, such as a lesser requirement propagules (stems) greater phytosanitary control seedlings, when compared to conventional planting. Commercial substrates are expensive their increases cost seedlings. This study aimed evaluate quality grown on with different proportions decomposed babassu palm stem (DBPS), well recommend substrate formulation that provides most favorable environment for growth development For preparation (S), DBPS soil were used following proportions: S1: 0 % + 100 soil; S2: 20 80 S3: 40 60 S4: S5: S6: soil. S2 S3 considerably improved seedling parameters, sprout diameter length, number leaves total, shoot root dry mass. However, from an economic point view, is recommended use.
